Specification of Letters Patent.

Patented Nov. 12, 1912.

To all; whom a may concern:

Be it known that I, Ennns'r Duscnnu,

La Crosse, in the county of La Crosse and State of Wisconsin, have invented a 1181 rand useful Improvement in Printing-Machines,

ticularly with a direct inking signature attachment to a printing machine 111 which While shown specifically applied to the general structure of printmg machine. set

invention involved may by slight lllOdlfiCt printing machines.

The primary object of this invention is the production of aprinting machine which will print from a ribbon and by Crcct inking sin'niltanedusly, thus in printing a type written letter on a ribbon press a signature may be also printed in ink directly.

Further objects of myinvention and advantages'attained thereby will be apparent from the following description.

In the accompanying drawings forming part ofthis specification, Figure 1" is a longitudinal section of a ribbon printing thereto: Fig. 2 is a transverse section taken detail in perspective; Fig. 14 a side elevation of my printing attachment removed from the printing machine, portions thereof being shown in section; Fig. 5 is a plan of the construction illustrated in Fig. 1; Fig. 6 is a plan of the inking roller and its sup porting means; Fig. 7 a side elevation of the construction illustrated in' Fig. (3; Fig. 8 is a side elevation of one of the guides which keeps the inking roller at alret er heightas is passes over the gage of the the. construction illustrated in Fig. 8 and Fig. 10 is a section of a/detail of the block and gage. I

thereby on the form.

For the purpose of clearlydefining my invention a brief description of the printing machine to which my invention is applied will bemade followed by a detail description of the signature attachment.

In the above drawings I have shown a printing machine having a supporting frame A, a type bed B carried by-said frame 011 which a type form C may be supported (see Fig. 2) and with which a traveling platen coiip erates in making a printing impresslon.

On the frame A are mount d sprocket wheels 2- carrying sprocket chains 8 at each side of the machine on'which chains is mounted the platen D in the form of a roller having a body 1 which traverses the type form and a wear wheel 5 at each end through which printing pressure is imparted to the platen. The type bed B is so positioned with relation to the path of platen D car ried by the sprocket chains 3 that the platen normally travels orbitally about the type bed, and above the surface of the type 'in the form and out of contact with it.

Printing pressure on the platen issecured by means of pressure bars fi ance-ch side of the machine under pressure from the spring 7 which may be adjusted to different degrees of pressure. The under surface of the pressure bar 6 is formed with rectangularnotches 8 which bear upon the periphery of the in tegral disk portion of wear wheel 5 (see Fig. 2) producing an intm'mittent pressure and repeated impacts on the platen and A tabulating rail 0 is shown ateach side of the machine on which rail the body portion of wear wheel 5 travels. The upper surface of the tabulating rail formed with a steel ribbon 10 mounted resiliently on it'by means of which ribbon local'adpistments of pressure on the form may be secured.

A color inking ribbon 11 is mounted on the machine between the path of the platen and the type form and is carried over suitable anti-friction rollers 12 through openings 13 in the type bed and has itscnds connected to feed and take up rollers 1 1 which serve to automatically step the ribbon over the type in the usual manner. The specific construction employed for stepping the ribbon is not illustrated in the drawings but can be found fully set forth in application Serial No. 638,388 filed on July 13, 1911 jointly William A. Sorg and myself and also in the application filed by William A. Sorg on J an. 8, 1908 Serial No. 437,302.

Paper lifters 15 which serve toassist in positioning the paper to be printed upon the type form and cause it to properly register with the type also serve tolift the rearward edge of the sheet of paper after each printing operation. The paper strippers such as 16 follow and catch the raised edge of the paper then removing the paper after it is printedfrom the machine; The strippers are mounted. upon the shaft 17 which extends between and .is supported by the chain belts 3 across the machine following afterthe impression roller. The shaft 17 is rigidly secured to the chain belts in a lug 18 on one of the links by means of a set screw 19. The paper lifters 15 are adjustablysupported upon the transverse shaft 20.

My signature attachment consists of a block E of comparatively narrow width and extending transversely across the type bed and parallel with the line of motion of the platen D, said block being adapted to be held in the type bed by the type'form in which it is locked. The block-rests directly on the type bed-B on which it. is adjustable .vertically by means of set screws 21, this adjustment being permanent when -'once made to bring its surface to such an elevation that standard type 22 in the main type form will have equal elevation with the type plate F which the block E is adapted to carry. The printing plate F which is commonly used for signaturesanay be in the.

form of; an etching orotherwise constructed and secured on the plate .23. It may when desired be made of type locked in a' form and the term printing plate is to beconsidered. in the claims following this specified;

tion as. covering such construction. The plate 23 is depressible that is it recedes un der pressure exerted down upon its surface by the platen while the ribbon 11 is interposed between the gage 23 and the block. The gage is in the Iform of a long narrow plate which is supported horizontally upon resiliently supported pins 24 which are pressed. upwardly by means of springs 25 stationcd in openings 26in the block. The upward movement of the gage 23 is permitted by means'ot'pins 27 extending from the ends of the block E and passingfrecly throughslots 28 in, the downturned ends of I the plate and islimited by the ends of the -as to incline rearwardly causing the ink-' through said space and feeding forward by the ribbon feeding mechanism.

Mounted upon the shaft 17 is an inking roller 30 which is journaled in the yoke 31 on the removable pin 32 said yoke being journaled on the shaft 17 and supported son's;

ing roller to trail after the shaft.- The in (-14, ing roller is pressed in a downward direc? tion by means of a dog 33 rigidly secured to the shaft 17 by the set screw and having secured thereto a coil spring 35 the ends 36 of'which bear down upon the yoke. The downward mt veinent of the inking roller is limited by the end 37 of the dog impinging against the cross piece or stop 38 on the yoke. The dog 38is set in adjusted posi tion on the shaft 17 by the screw 34 so that the inking roller30 will have free m0ve- Y Inent over the printing plate F during the normal operation of the machine and at the same time limit movement of the niking roller when traveling out of contact with the inking block and plate F. The pin 32 is held in the yoke by means. of a catch 39.-

Secured to the shaft .{=1 at each end in position to travel over thearailt) is a guide arm 40 said arm being fastened in adjusted position on the shaft 17 by means of a set screw 4.1, the free end of said arm having an anti-friction roller 42 hearing down upon the surface of the tabulatingrail 10 and serving by its-adjustment to keep the inking roller at an even height as it passes over the gage 23. This adjustment can be varied so that the inking roller will evenly ink the 10( printing plate and will not come into contact with the gage 23 thus preventing smutting of the material which is being printed upon through contact of the' inking roller with said gage.

Secured to the forward end-of the block E is an auxiliary block H which carries an ink- :i'ng fountain I. The auxiliary block H has,

in its outer'extrcmity a cavity43 in which is journaleda fountain roller 4:4: with the surface of which the inking roller 30 is adapted to contact each printing operation of the machine and to carry the ink transmitted, by the roller 44 from the fountain to the ink distributing surface 4-5 which is formed on the auxiliary block H. In this manner ink is evenly distributed over the surface of the printing roller 30 before it is applied to the surface of the printing plate FL. Fountain roller 44 is freely journaled in the sides of the fountain and is revolved forward at step each time the inking roller 30 coiiperates with it by means of the sprocket wheel 46 carried by the shaft 47 of the fountain wheel and a tooth 48 extending down 12.5 from the side of arm 519 of theyoke 31 in which the inking roller 30 is journaled and adapted to mesh with the teeth of the sprocket. A flat spring secured to the frame of the fountain I by means of screws 51 presses evenly upon the periphery of the roller 44 and serves to adjust the quantity and evenly distribute theink upon the periphery of the fountain roller 44. Longitudinally disposed adjacent to each side of the distributing surface 45 is a raised guide rail 52 made of fiber or other suitable material suitably secured to the arnts 53 and adapted to form a track upon which the body of the impression roller D rolls when passing over the ink distributing surface 45. These guide rails 52 being raised above the surface 45 joint, the tongue 55 57. A setscrew 58 passing up from below through the tongue below 'the slot impinges a against the pin .56 for the purpose of assisting in holding the parts together.

oint permits the outer end of the auxiliary block 'H to be adjusted in height and also permits the blocks E and when desired. The auxiliary block H is ported upon the H being separated formed with a loop 59 passingfreely below the paper lifter shaft 20 and the outer end of the auxiliary block H is adjustably supshaft 60 which carries a pair of sprockets 2 by means of, a tilting arm 61 which rests uponsaid shaft. This arm is pivoted to the auxiliary block at 62 and its outer end carries an upwardly extending bolt 63 locked in adjusted position in the arm 61 by means of lock nuts 64 1' with its end impinging against andsupportlution of i the arrow direct, inking. lowing the platen engage and remove the .co

ing the auxiliary block. Thus by adjusting the bolt 63 in the arm 61 theheight of the fountain end of the auxiliary block may be adjusted so thatthe inking roller will touch 44- lightly and thus asproper quantity of ink the distributing of ink surface so.

printed is placed upon the iribbon dver the type form and over the printing plate -.F it being properly adjusted against the paper to register with the type. Revothe chain belts in the direction of indicated in Fig. 3 causes the impression roller to cooperate with the ty-pein the form and produce a printing impression including the printing of the signature by j The paper strippers 16 follifters 15 paper off of he form, the paper lifters hav i lg previously lifted the rearward edge of v the paper into engaging position for thestrippers. The inking roller. passing over the fountain carries ink onto thedistribut- The auxiliary block This - printing nally against the pins ing surface 45 and while traveling over the distributing surface receives an even coating of ink which in turn is transmitted to the printing plate F which isinked in readiness todeliver another printing impression during the subsequent impression of the platen. While the platen is cooperating with the type in the main form and with the printing plate F to produce printing from both simultaneously, the ribbon remains stationary and the gage 23 carrying the printing plate F is pressed down by contact with the platen; printing surface of the plate as that of the rint: ing surface of the main form of type. As soon as the impression element passes out roller until the F lies in the same plane of cooperation with the gage 23 said gage and plate resume normal position as illustrated in Fig. 4, leaving a space between the gage and surface of the block E'through which the ribbon is free to be fed forward before a subsequent printing operation of the machine. v

To hold the paper ormaterial being print- I ed upon out of contact with the printing plateF Wl11l8 the parts are not actually making an impression in the-form of a spring -arm projecting upwardly above the surface of the plate F is secured bv means of a screw 66 to the surface of the gage adjoining said plate. This lifter 65 supports the paper normally above the plate F but is depressed by force'exerted against the paper as.the impression element passes into cooperation with the forms.

The printing plate F is secured to the gage 23 by means of screws (37 threaded thereinto, said gage being provided with a series of screw holes (58 so spaced apart and disposed longitudimllly in a row as to receive thescrews (35 and (i7 and position the in the type form on the type bed thus eauhing printing of the signature in the desired position below the closing compliments of a letter.

When insertinghlock E in the form the auxiliary block l l is detached and the gage 2 3 removed from the block so that the ribbon may be passed over the block E. To remote the gage. it is pushed longitudithe tension of the spring 70 which pressesagainst the dmvnwardlybent end 71 of the through which one of 27 projects." The movement re leases the opposite downwardly bent end 72 of the gage 23 from engagement with the opposite pin 27. adjusted over the block E and the main type form the gage 23 is re-adjusted to the block by reversing the operation just described.

The auxiliary block H is then reattached After the'ribhon has been and for the purpose of preventing smudgmg, a paper l fter 65 plate I and litter (36 as desired to the end of block E. These adjustments are easily and quickly made Without. the inconvenience of disconnecting one end of the ribbon from the ribbon rollers.

The inking roller 30 carries one or more guards 73 secured to the yoke frame 31 such as by screws H and serving to prevent clothing of the operator or paper from coming into contact with the inking roller and soiling as the roller travels orbitally about the bed of the machine.

While the chain belt has been described as being equipped with one platen roller and an inking attachment which is adapted to cooperate with the printing plate it will be understood that one or more impression rollers and accompanying inking attaclnnents 1r iy be mounted upon the belt to increase the relative speed of printing.
